The PE filler masterbatch is High Density Polyethylene (HDPE), which is a highly crystalline, non-polar thermoplastic resin. The original HDPE has a milky white appearance and a semi-transparent shape in a thin section. PE has excellent resistance to most living and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. HDPE has excellent electrical properties, especially high dielectric strength, making it suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance, both at ambient temperatures and even at temperatures below -40 degrees Celsius.
Combustion characteristics; PE filled masterbatch is flammable, can continue to burn after fire, the upper end of the flame is yellow, the lower end is blue, it will melt when burned, there will be liquid dripping, no black smoke will emerge, and at the same time, when paraffin is emitted, it will be emitted.
Main advantages; acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and can maintain a certain toughness at low temperatures. Surface hardness, tensile strength, rigidity and other mechanical strengths are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.
Main disadvantages; poor mechanical properties, poor air permeability, easy deformation, easy aging, brittleness, brittleness lower than PP, easy stress cracking, low surface hardness, easy to scratch. Difficult to print, when printing, surface discharge treatment.
Application; PE filled masterbatch for extrusion packaging film, rope, woven bag, fishing net, water pipe; injection low-grade daily necessities and outer casing, non-load bearing members, plastic boxes, turnover boxes; extrusion blow molding containers, hollow products, bottles .
